She sang about having to wake up alone, but tragically that is how she died instead.

Famous for the defiant song, 'Rehab' Amy Winehouse died alone, at home, watching YouTube clips of herself after drinking two bottles of vodka.

An inquest into the troubled singer's death found what has already been widely reported; that the 27-year-old died of alcohol poisoning in her London home on July 23, 2011.

Miss Winehouse drank so much that she stopped breathing and fell into a coma, The Daily Mail reported.

While her live-in body guard was home and had seen the Grammy-award winning singer earlier in the evening, he insisted to the courts that she was her 'usual, bubbly self' and while he could tell she had been drinking, she 'wasn't completely drunk'.

According to the body guard, Winehouse, who was struggling with alcoholism, bulimia and who was a recovering drug-addict, spent the night watching television and listening to music in her bedroom.

In a statement read out at court, he said he had left her around 2.30am before checking on her again at 10am. Lying fully-clothed, face-down in bed, he believed she was sleeping. He realised there was a problem when he found her in the same position at 3pm that same day and alerted emergency services.

She was pronounced dead shortly after paramedics arrived.

Pathology tests showed she had 416 mgs of alcohol per decilitre in her blood – 350mg is enough to kill.

The death was described as a 'misadventure' by the coroner.

This was in light of a statement by Winehouse's doctor, who said: "In the course of the last consultation, Amy did not appear to be depressed at any stage... She specifically said she did not want to die."

This was the second inquest into the singer's death. The first inquest was rescheduled after it was found the original coroner was underqualified.

Winehouse wrote her first song as a 10-year-old and learned to play guitar when she was a teenager.

She went on to win six Grammys from her album Back to Black which documented her personal problems.

Her father Mitch has previously said she was working hard to overcome her troubles and described his daughter as "a lovely, funny girl."
